Nakajima began developing the Ki-84 in 1942, offering improved firepower and tougher armor than the company's Ki-43. Heavily armed with two 12.7mm machine guns and two wing-mounted cannons, the "Frank" was an equal in theory for anything fielded by the Allies. In practice, however, Japanese pilots were being rushed into the air with inadequate training and supplies of gas, parts and ammunition were low. The full potential of the Ki-84 wasn't realized until the Allies tested it after the war. Limited edition kit features two Hitachi Flight Training Division decals.
